I am in the process of creating an activex control for PocketPC. I am having problem in getting a focus rectangle when a button in the control gets focus.
Any help?

The Pocket PC does not show a focus rectangle like you see on the desktop.

If PocketPC doesnot show FocusRect, then is there any way we change the control appearance to show th euser that control has got the focus? Any idea on this ?

When you click a button, it retains its focused state (unless you change it). This is visually shown as a double border (even if you tab through a series of buttons).

Hi,
Thanks for the reply.
But when I create BUTTON control in eVC++ , it does not reflect the border when it is in focus( particularly when I test the ocx in eVB). The objective is to use the button ocx in eVB, so that when the user navigates through keyboard in PocketPC, the focus status is shown.
The following code draws the focus rect when in focus, but the application crashes after the focus is lost.
void CMfcnewCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC *pdc;
CPen* pOldPen;
CRect rcSrcBounds;
RECT rect;
SHORT inflate;
pdc = CDC::FromHandle(lpDrawItemStruct->hDC);
switch (lpDrawItemStruct->itemAction)
{
case ODA_DRAWENTIRE:
case ODA_SELECT:
case ODA_FOCUS:
// Just draw focus rect
pOldPen = (CPen*)pdc->SelectStockObject(BLACK_PEN);
if (lpDrawItemStruct->itemState & ODS_FOCUS)
{
CopyRect((LPRECT)&rect, (LPRECT)&lpDrawItemStruct->rcItem);
inflate = (SHORT)min(3,min(rect.right - rect.left + 1,
rect.bottom - rect.top + 1) / 5);
InflateRect(&rect, -inflate, -inflate);
pdc->DrawFocusRect(&rect);
}
pdc->SelectObject(pOldPen);
break;
}
}

Why My pocket PC makes new columns with counter???
For example i have the table with columns:
PointID - counter;
X int;
Y int;
and when i copy this database to pocket and get it back to Desktop PC i got this:
Point ID - int;
X -int;
Y -int;
ID1 - counter;
Where is the problem???

Try using the Pocket Access option on ActiveSync to synchronize your databases.
What is happening is that when you copy the Access file to the Pocket, it will lose all unique indexes and counter fileds. They will become integer fileds with a non-unique index (read the ActiveSync help on this). When you copy it back to the desktop, the conversion mechanism seems to automatically create a unique ID field for the table.
When synchronizing databases through ActiveSync, this problem never happened to me.

How can I create a Installer for my evc-PPC2002-MFC-Program? Most programms come with installers that you start on the desktop and that copy all required filed to the device via ActiveSync.
Are there tools for doing that? Maybe free tools? Or is it include in eVC somewhere? thx..
thx, Daniel

You install applications on a pocket PC using a two step approach.
First, you have to create a setup cab file. Information for this is available on the SDK help, but you can find a sample here:
QA: How can I install ADOCE 3.1?[^]
Next, you have to copy the cab file to the Pocket PC and execute it. You can do this manually or through ActiveSync's Application Manager. Search the "Registering with Application Manager" item on the SDK help.

you can sync data using wireless or wired options. In either ways you can get connected to the server.
Types of options you can have
1. Wireless
2. Wired - via Modem to internet, or LAN
It works fine with all these options..

Hi,
Can you please explain more about wireless communication, and how it can be done using .NET compact framework.

Mahesh,
Look into Bluetooth, as it already supports Active sync over Bluetooth.
And many PDA's like iPAQs come preintalled with bluetooth and Windows CE supports bluetooth API as well that you can use.

I have some question about CADORecordset.
I've got the code like this:
void CAccessLayer::Repaint()
{
CADORecordset rs(&g_db);
CString Query;
Query = "SELECT * FROM Points WHERE LayerID = "+m_LayerID;
int X;
int Y;
if(rs.Open(Query,CADORecordset::openQuery))
{
rs.MoveFirst();
for(int i = 0; !rs.IsEof(); rs.MoveNext(), ++i)
{
rs.GetFieldValue(_T("X"),X);
rs.GetFieldValue(_T("Y"),Y);
X=(_BitmapWidth*(_rotate*X - _ViewLeft))/_WR;
Y=(_BitmapHeight*(_rotate*Y - _ViewTop))/_HR;
_BitmapCanvas->Ellipse(X-100,Y-100,X+100,Y+100);
}
}
rs.Close();
}
but i use this function very often, and i'd like to place the query in the constructor of the class. And i want to call in the function only this:
void CAccessLayer::Repaint()
{
rs->MoveFirst();
for(int i = 0; !rs->IsEof(); rs->MoveNext(), ++i)
{
rs->GetFieldValue(_T("X"),X);
rs->GetFieldValue(_T("Y"),Y);
X=(_BitmapWidth*(_rotate*X - _ViewLeft))/_WR;
Y=(_BitmapHeight*(_rotate*Y - _ViewTop))/_HR;
_BitmapCanvas->Ellipse(X-100,Y-100,X+100,Y+100);
}
}
And in constructor i have this :
rs = new CADORecordset(&g_db);
CString Query;
Query = "SELECT * FROM Points WHERE LayerID = "+m_LayerID;
rs->Open(Query,CADORecordset::openQuery));
But my programm doesn't work. Is it necessery to have CADORecordset locally???
Thaks.

Is g_db initialized when the constructor is called?

Hi All,
I have an Inventory application running on the desktop(Developed using C#). I'm planning to write one for PDA( Using C# & .NET Compact Framework). But the issue is that, i want to synchronize data between the destop application and the handheld application.IR communication is not possible, as it is limited for a very short distance.
Can any one throw light on other communication options available( like GPRS, wireless etc..).
Thanks in advance

How to create a Console Application in eMbedded Visual C++ 3.0 for Pocket PC emulation
Thanks.

The Pocket PC does not support native console applications. You have download a third party console.

I use the File Open dialog from an article on CP, and it works fine when used form my app class.
Weirdness, Part 1 - In our app, we have a listview. One of the contxt menu items needs to call up this dialog box also. However, the dialog box displays, but locks up when called from the listview.
Weirdness, Part 2 - If I put a call to AfxMessageBox in the dialog's OnInitDlg() function, the dialog box works fine after I dismiss the message dialog. If I don't display the message dialog, the dialog box locks up.
Weirdness, Part 3 - The "X" button in the titlebar doesn't work, but the SIP does, and I can dismiss the dialog box by clicking the ENTER key in the SIP.
Anyone have any hints?

Are you using property sheet/pages and dialogs, or just dialogs ?
They all sound like the same problem - the new dialog isn't getting the focus when it should.
I've had something similar happen when, for instance, i created a dialog resource as a property page, then changed my mind and used as a CDialog without changing the resource properties from child to popup. Also make sure the new dialog isn't overlapped, i think that only the main app dialog can safely be overlapped (cound be wrong - have't checked).
For Part 3 : the X is part of the dialog/page, the SIP isn't, hitting enter in the SIP just acts as if you hit the default button on the dialog/page - usually IDOK.
On an unrelated note, here are some other things i've found :
There is a bug in MFC CPropertySheet::ContinueModal(), so in any PS derived class' override with :
class CkDlgEdit : public CPropertySheet
...
BOOL CkDlgEdit::ContinueModal()
{
if( !CWnd::ContinueModal() ) return(FALSE);
return(TRUE);
}
There is a resource leak when displaying a dialog box. The following methodology evidently prevents this :
void CJsoFldCeDlg::OnDblclkList( NMHDR *pNMHDR, LRESULT *pResult )
{
...
{
CkDlgEdit dlg(this, L"Edit Observation");
dlg.DoModal();
}
AfxGetApp()->OnIdle(1);
...
}
...cmk

Try inserting this on the OnInitDialog handler right after the call to the base class' handler:
if(::GetCapture())
::ReleaseCapture();

I've had a search around and I'm at a bit of a loss... So here goes...
Background: I have a Pocket PC application that creates XML files. The PPC application reads and writes them using XmlTextReader/Writer. These files can be synchronised through ActiveSync and a desktop application allows the data to be reviewed before going in to the database.
Situation: Now, the data is to communicate with a Web Service. Since I already have the XML structure defined is there anyway I can put that across to the server without ending up with lots of > and < etc.? At the moment I define the data type in the Web Service as a string and copy the contents of the file into the string and send it across.
